MARKER FOR POSTMARKING AND STAMP-CANCELING MACHINES.

SPECIFICATION forming part of Letters Patent No. 561,573, dated June 9, 1896.

Application filed September 22,1891. Serial No. 406,43 7. (N0 model.)

To allwhom it may concern} Be it known that I, MATTHEW J. DOLPHIN, of Brooklyn, in the county of Kings, in the State of New York, have invented new and useful Improvements in Markers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in markers as impression-rollers, adapted particularly for use in machines for postmarking and stamp-canceling mail-matter, and has for its object the production of a simple and effective construction, which in use is convenient, strong, and durable.

To this end the invention consists, essentially, in a frame formed with a socket, having a movable wall and a die or type carrying box or frame removably mounted in said socket and adapted to be held in position by said movable wall.

The invention furthermore consists in a type-carrying box having a shoulder at its outer extremity for bearing against the marker-frame, in seats provided in opposite side walls of the typeparryingbox and adapted to receive projections upon adjacent walls of the marker-frame, in a block or wedge for forcing the movable wall of the socket into operative position, and in the detail construction and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figures land 2 are respectively top plan View and elevation of my improved invention. Fig. 3 is a transverse horizontal sectional view taken on line a: 00,'Fig. 2. Fig. 4 is an elevation of the parts as illustrated in Fig. 2, a portion of the marker being removed and the movable block for forcing the movable wall of the socket into normal position being shown as in its inoperative position. Fig. 5 is a transverse vertical sectional view takenon line y 3 Fig.2. Fig.

6 is a similar sectional View to that shown at Fig. 3, representing the movable wall as open to permit removal of the type-carrying box. Figs. 7, S, and 9 are respectively front, rear, and side elevations of the die or type carrying box or frame. Fig. 10 is an isometric perspective of the fixed wall or shoulder at the rear of the movable wall of the socket, and Fig. 11 is a face view of the print or impression produced by my invention.

Markers as printing-rollers for machines adapted to postmark and stamp-cancel mail matter are revolved or operated with great rapidity, and in some classes of such machines are stopped after each operation or registration. Consequently the marker should be very light and also strong and durable. Moreover, as the type must be continually changed for indicating the day and the time the mail is received or its stamp canceled the marker or impression-roller must be very convenient in order that a postal clerk of the ordinary mechanical capacity, instead of a skilled machinist, may attend to its adj ustment, and the type must necessarily be easily removed and firmly held in position. My invention is designed to possess these valuable requirements, thus combining lightness, d u rability, simplicity, and convenience.

A represents the marker-frame consisting, preferably, of a pair of substantially circular disks Ct a and a central sleeve or journal bearing a, for receiving a shaft, (not illustrated,) adapted to rotate the marker or printing-roller and effect its registration with the mail-matter.

At Fig. 11 I have shown the preferable form of print or impression produced by my marker, which consists of a series of bars B, having at one side thereof a circular mark or impression B, Within and next to which are the characters B representing the year and the city and state at which the marker is used, and at the center the characters 13 for indicating the month, day of the month, and the hour of the day. The bars are printed by projections or ribs b upon a plate Z), secured by screws 1) to the disks a a, and the circular impression or markBby a rib c on the outer face of a box or type-carrying frame 0, removably mounted in a socket A in the frame A. The characters B L are printed, respectively, by the stationary and removable letters B B (Shown at Figs. 2, 7, and 9.)

The top and bottom walls of the socket are formed by adjacent faces of a portion of the plates a a, the rear wall by a face a on the sleeve a, and the side walls by plates or walls D and D, secured between the plates Ct a.

As presently described, one wall D of the socket A is movable in order to permit the entrance of the box or frame 0 and to firmly retain the same in operative position.

The box 0, as best illustrated at Figs. 7 8, and 9, consists of the essentially rectangular rear portion 0 and the slightly-oblong outer portion 0 which is of greater diameter than the width of the inner rectangular portion 0, thereby forming a shoulder 0 adapted to bear firmly against a shoulder A formed on the outer face of the disks a a and the walls D D The outer and inner portions of the die or type carrying box or frame 0 are formed integral of the same piece of metal and are provided with a central socket or cavity 0, open at the front and closed at the rear by a removable plate 0 The type B for indicating the month, day of the month, and the hour of the day, are removably mounted within the socket 0, since these type must be continually changed, and on the inner face of the circular rib or projection c, for forming the round impression or mark B, are the stationary type B representing the city, the state, and the year, which type are formed integral in relief on the outer face of the box C.

For the purpose of enabling the type to be readily interchangeable and causing them to be extremely firm in position they are formed with essentiallyparallel sides, and the socket O is also formed with essentially parallel sides.

The removable type B are preferably arranged in two rows, one above the other, and formed in their adjacent faces are the opposite halves of a groove F, adapted to receive a pin f, which passes through the side walls of the box and when in operative position firmly holds said type. As the pin f is forced from position the type B may be readily removed by forcing a suitable instrument through openings 0 in the rear wall of the type-carrying box.

As previously stated, the wall D of the socket A is movable in order to permit the entrance of the die or type carrying box or frame 0, being preferably hinged at its rear extremity upon a pin d and provided at its outer extremity with projections d, adapted to engage sockets d in the adjacent face of the die or box 0.

At the outside of the free end of the 1novable socket-wall D is the fixed wall or shoulder D consisting of an upright bar secured to the disks a a at its opposite extremities by pins (Z and provided on its upper portion with the inner inclining face D an inwardlyextending stop-shoulder D beneath said face, and a recess D on its inner face beneath the shoulder D as best shown at Fig. 10.

G represents a block movable between the wall D and the upper face D of the shoulder or bar D for firmly forcing said wall D into engagement with the die or type carrying box 0 and movable into the recess D of the bar D for permitting the wall D to be moved away from the type-carrying box when desired to remove said box. This block consists, preferably, of a lever having one end hinged at g to the rear extremity of the wall D and the other end movably mounted be tween the face D and the adjacent extremity of the wall D.

G represents a spring having one end secured to a pin 9 upon the rear end of the wall D and the other bearing against the lower face of the block G for normally forcing the same into operative position, as illustrated at Fig. 2. On the upper face of the block G is a shoulder 9 with which a narrow instrument, as a knife, screwdriver, &c., may be engaged for forcing the block downwardly and then outwardly into engagement with the shoulder D whereupon the wall D maybe readily forced outward, as shown at Fig. 4, and the die or type carrying box 0 removed for the purpose of cleaning, changing the letters, &c. To aid this outward movement of the wall D, I provide a spring II, having one end coiled around the pivot (Z and adapted to bear against the wall D and the other bearing against the sleeve Ct. It will be understood also that, if desired, a spring may encircle the sleeve a with one end bearing against the rear face of the box 0 for forcing the same outward when the wall D is forced outward, as previously stated.

In order to retain the die or type carrying box or frame 0 very firmly, I provide pins (1" upon the fixed wall D of the socket A and corresponding seats in the adjacent face of said box 0 and form in the lower edge of the box grooves 01 which receive the pins (1 and enable the box to readily pass to its operative position.

Upon reference to the drawings and the foregoing description it will be noted that the die or type carrying box or frame when in position is held extremely rigid, since two opposite sides of its inner portion a are ongaged by projecting pins on the adjacent walls of the socket A, that the shoulder c bears against the shoulder A and forms a firm abutment for the die when impinged against the letter, and that the entire die may be removed for cleaning or replacement with a new die or for readjustment or replaceir ent of the movable type.

The operation of my marker will be readily perceived from the foregoing description, and it is evident that considerable change may be made in the detail construction and arrangement of the parts without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
